User's Manual
the device answers with a Facility IE message with the
Reject component on receipt of Facility IE with
unknown/invalid Invoke component. This bit is implemented
in QSIG and ETSI variants.
Determines the bit map for special PSTN behavior parameters:

[0] = (Default) Applicable for NI-2 ISDN and QSIG
"Networking Extensions". This bit (i.e., bit #0) is responsible
for the Invoke ID size:

If this bit is not set (default), then the Invoke ID size is
always one byte, with a value of 01 to 7f.

If this bit is set, then the Invoke ID size is one or two
bytes according to the Invoke ID value.

[2] = Applicable to the ROSE format (according to the old
QSIG specifications). This bit (i.e., bit #1) is responsible for
the QSIG octet 3. According to the ECMA-165 new version,
octet 3 in all QSIG supplementary services Facility
messages should be 0x9F = Networking Extensions.
However, according to the old version, the value should be
0x91 = ROSE:

If this bit is not set (default): 0x9F = Networking
Extensions.

If this bit is set: 0x91 = ROSE.

[3] = Use options [0] and [2] above.
Note: For the parameter to take effect, a device reset is
required.
Defines Point-to-Point (P2P) or Point-to-Multipoint (P2MP)
mode for BRI ports.

[0] Point to Point (default)

[1] Point to Multipoint = Must be configured for Network
side.
Defines the BRI terminal endpoint identifier (TEI) when in
point-to-point (P2P) mode.
The valid value is 0 to 63, 127. The default is 0.

Network Side:

0-63: Static TEI is accepted.

127: Any possible TEI is accepted. Dynamic TEI
allocation is supported.

User Side:

0-63: Static TEI is used.

127: Dynamic TEI allocation is supported (TEI request
procedure initiated).
Note: The value 127 replaces the previous configuration
requirement to set the ISDNIBehavior parameter to NS
EXPLICIT INTERFACE ID (1).
Defines the BRI TEI when in point-to-multipoint (P2MP) mode.
The valid value is 0 to 63, 127. The default is 127.

Network Side: Not applicable - In network side in P2MP
configuration, any TEI must be accepted.
